Why is the PHP-FPM error log not displayed under Nginx?

I configured the LNMP environment under Ubuntu, where Nginx is configured with error logs and access logs, everything is normal.

At the same time, PHP-FPM configures error_log in pool/www.conf.

<code>catch_workers_output = yes

php_admin_value[error_log] = /home/liyi/logs/php-error.log
php_admin_flag[log_errors] = on</code>

At the same time, I print phpinfo(); as shown below:

But my php-error.log has no error log. Instead, the php fatal error message is printed in the nginx error log.

Nginx error log is as shown below:

PHP error log is completely blank.

I switched to the Homestead virtual machine and everything was normal, and the php error_log was displayed normally.
